摘要

Teeth meshing stiffness was calculated using tooth contact analysis and load tooth contact analysis. A 12-DOF nonlinear double helical gear vibration model was established considering excitations of time-varying meshing stiffness, corner mesh impact, and backlash. With a ship transmission system as an example, the vibration characteristics of the left end meshing gear pair under multi-load were studied. The results showed that the system vibrations under excitations of meshing stiffness and corner mesh impact increase with increase in load torque; a corner mesh impact excitation is more sensitive to changes of load than a meshing stiffness excitation; however, the vibrations of the system decrease with increase in external load under backlash excitation; meanwhile, a corner mesh impact has a growing effect on the system vibrations with increase in the load while a meshing stiffness and a backlash excitation have diminishing effects.
